Figure 5.

Effect of ABA treatment on root morphology. (A) Seedlings of 3 DAG were transferred to Hoagland solution with 0, 1, 3, and 6 µM ABA concentration. After 4 days of treatment, we photographed the seedlings and measured their seminal root lengths. Bar = 2 cm. (B–E) Statistical analysis of shoot (B) and root (C) lengths and relative length of shoots (D) and roots (E) for seedlings in (A) by normalizing with each 0 µM control. Three biological replicates were included. a, b, c, and d indicate the significant differences obtained via two-way ANOVA, where p < 0.05.
